LAST.

Specification of Letters Patent.

Patented sept. 17, 1907.

Application filed February 19, 1907. Serial No. 358,222.

To all whom t may concern:

Be it known that I, HIRAM WAIDE MARDEN, a citizen of the United States, residing at Lynn, in the'county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Lasts, of which the following is a specification.

This invention is an improvement in shoe makers lasts, and has for its object to provide the last with means for holding the shoe inner-sole against displace* ment laterally while the operation of lasting the upper is being performed and with el'licient locking means for securing the last block and last together.

In the drawings Figure l shows the last which embodies my invention, and Fig. 2 shows the top of a fore part section of the last.

ln carrying out this invention the last is provided with chambers a. In these chambers a are located the sole holding devices Said devices respectively comprise a shaft b having one end sharpened to a point and adapted for projecting through an opening C in the iron plate d which covers the last bottom. The other end of the shaft b extends upwardly so as to engage with the last block e. Onthe shaft bpis a spiral spring j, which bears one end on the plate d and one end on the plate n which is fixed to the shaft b, so that the spring operates for retracting and retaining the shaft b in the chamber a, and with its end projecting above the face of the last A, whenever the last block e is not in place to prevent it.

The point or fore-end of the block c is held in place by a screw m which, for that purpose, is fast in the last A. It has a fiat head and is arranged relatively for the end of the block e to project under one side of the head and thereby it holds the end of the block e from lifting away from the last A while the block is suitably recessed for receiving the head of the screw and thereby it is secured against displacement laterally in relation to the part A. The part A has a hole h and in a suitable hole of the block e is a bolt B. Connected with the bolt is a pull strap c. On this bolt is a spiral spring which bears one end on the bushing 3 and the other end on the plate 2 which is fixed to the bolt, so that the spring operates for driving the bolt forward into the hole h of part A. Preferably the hole h runs acutely angular to the longitudinal plane of the last, and it and the bolt B and last parts are thus relatively dis posed so that when the bolt is projected into the hole h, the block e being then in close touch with the last A, it operates for locking the block e against possible displacement, and holds it tightly down to the last A.

The shafts b, it will be understood, are forced downwardly and held with their pointed ends projected through the last bottom by means of the block e, and in the block e are metallic studs 4 for the shafts b to bear against and thus the wood material of the block is protected. i i

The block e may be unlocked by pulling the strap la, thereby drawing the bolt B from the hole h. way I obtain an economical and at the same time a most effective means for locking the block e and the last A together, and for supporting the block against all possible displacement because of any pounding or force applied to the sharp ends of the shaft b.

The sharp ends of the shafts b are intended for entering the inner-sole when it is placed upon the last In this bottom preparatory for the lasting of the upper and they are, therefore, disposed preferably one in the shank and others in the ball portion of the last.

I" claim 1. Thecombination with a last, the top of which is cut away in the usual manner, and spring-actuated pins movahly secured in orifices which extend from the cut away portion of the top to the bottom surface of the last, said pins being of greater length than their respective orifices whereby they always protrude through either the top or bottom surface of the last, of a last block, the inner surface of which corresponds in shape to the cut away surface of the last and is adapted to bear directly upon the upper protruding ends of the pins and meuns for securing the last block to the last.

2. The combination with a last, the top of which is cut away in the usual manner, and spring-actuated pins movably secured in orifices which extend from the cut away portion of the top to the bottom surface oLthe last, said pins being of greater length than their respective orifices whereby they always protrude through either the top or bottom surface of the last, of a last block, the inner surface of which corresponds in shape to the cut away surface of the last, and having studs extending flush with the inner surface of the last block and located in position to engage the upper protruding ends of the spring-actuated pins, the last and last block having holes Which run acutely angular to the longitudinal plane of the last, and a springactuated bolt adapted to enter said holes whereby to lock the block to the last in a direction at an angle to the path of movement of the spring-actuated pins.
